Property in Louisiana is valued by an elected parish assessor, not by a state office or a city hall. That one fact explains most of what you need to know before you pick up the phone. Louisiana is organised into 64 parishes rather than counties, and each parish has its own assessor with its own staff, hours and phone number. Some of our database labels use the word "county" for consistency, but the offices themselves are parish offices. This page covers 78 assessor listings, and the sections below explain what those offices do, how they differ across the state, and how to get a task done quickly.

Who Runs Assessor Offices in Louisiana Parishes

Each parish elects one assessor to a four-year term. The assessor lists and values every taxable property in the parish, including homes, farmland, commercial buildings, industrial plants and business equipment. The Louisiana Constitution and Title 47 of the Louisiana Revised Statutes set the rules, and the Louisiana Tax Commission supervises assessors statewide.

The assessor does not set tax rates and does not collect money. Rates, called millages, are set by taxing bodies such as the parish government, school board and special districts, and voters approve many of them. The sheriff, serving as ex officio tax collector, mails and collects the bills.

That split matters when you call. If your question is why your property carries a certain value, call the assessor. If it is how to pay, you need the sheriff's tax office. If it is why a millage went up, the assessor can explain the formula, but the rate came from a vote or a governing body.

The Jefferson Parish Assessor on Elmwood Park Boulevard, the E Baton Rouge Assessor at 300 North Boulevard in Baton Rouge, and the Vermilion Parish Assessor's Office on North State Street in Abbeville all work under the same statutes. What differs is staffing, online tools and how long the line is.

Louisiana Assessment Ratios, Reassessment Cycles and Exemptions

Louisiana does not tax full market value. The Constitution sets assessment ratios: 10 percent of fair market value for land and residential improvements, 15 percent for other property such as commercial buildings and business equipment, and 25 percent for public service property such as pipelines and utilities. The Louisiana Tax Commission, not the parish assessor, values public service property. The millage is then applied to the assessed figure.

Assessors reappraise on a four-year cycle. Between cycles, values still change when you build, demolish, add a room, split a lot or change ownership. When reappraisal raises values, state law requires taxing bodies to roll millage back so the total collected does not rise on reappraisal alone, unless the governing body takes a formal vote to restore it. Your bill can still rise if voters pass a new millage.

Every year the assessor opens the roll for public inspection, usually in the fall. This is your window to check the description, square footage, land size and exemptions on your parcel. Start with an informal conversation at the assessor's counter. If that fails, you can take the dispute to the parish Board of Review, then to the Louisiana Tax Commission or district court. Deadlines are short, so ask for the dates in writing.

Ask for your property record card as well. It shows how land, buildings and other improvements were counted, and most errors, such as the wrong number of bathrooms or an outbuilding that no longer exists, show up there first.

Homestead, Senior Freeze and Agricultural Use Programs

The homestead exemption covers the first $75,000 of market value on an owner-occupied primary residence, which is $7,500 of assessed value at the 10 percent residential ratio. It applies to most, though not every, levy, so ask how it appears on each line of your bill. You apply once at the assessor's office, and it generally carries forward until ownership or occupancy changes.

Homeowners aged 65 or older, and certain disabled owners, may qualify for a special assessment level that freezes the assessed value of their home, subject to income limits. Landowners can also ask about present-use valuation, which values qualifying agricultural, horticultural, marsh and timber land by its productive use rather than its sales potential.

Metro Assessors versus Rural Parish Offices in Louisiana

Louisiana's assessor offices vary far more in size than in legal duty. In the metro parishes, the assessor handles a high volume of sales, new subdivisions and commercial appeals. The office in Jefferson Parish County at 1221 Elmwood Park Boulevard, reachable at 504-736-6370, serves one of the busiest property rolls in the state. The office in East Baton Rouge Parish County at 300 North Boulevard, 225-389-3920, covers the capital region. The St Tammany Parish Assessor's Office at 701 North Columbia Street in Covington, 985-809-8180, serves the north shore of Lake Pontchartrain; see also the St. Tammany County page.

New Orleans has four listings, more than any other city in our database. Because several offices and addresses can look similar, confirm which one handles your property and district before you drive.

Rural parishes work differently. Bienville Parish keeps its assessor at 100 Courthouse Drive in Arcadia, 318-263-2214, and Morehouse Parish is on East Jefferson Avenue in Bastrop, 318-281-1802. Staffs are smaller, which often means a more personal conversation but fewer online services. Phone first, and ask what hours the office keeps.

The assessor is not always in the town you expect. Lafourche Parish's seat is Thibodaux, yet the Lafourche County assessor sits at 16241 East Main Street in Cut Off, 985-632-6933. Rapides Parish is at 701 Murray Street in Alexandria (318-448-8511), and Tangipahoa Parish is at 110 North Bay Street in Amite City (985-748-7176). St. Mary Parish lists only PO Box 264 in Franklin, so call 337-828-4100 for a street address before a walk-in visit.

Coastal parishes such as Plaquemines (Belle Chasse), St. Bernard (Chalmette) and Cameron add another layer. Hurricane damage, elevation and rebuilding all affect value, and staff there regularly field questions about damaged structures. If a storm damaged your home, ask whether an adjustment applies for the year in question and what documentation the office wants.

What to Bring and When to Visit a Louisiana Assessor

A short visit goes faster with the right paperwork. Bring these items:

Call before you go. Offices generally keep weekday business hours and close on state and federal holidays, and Mardi Gras Day is a legal holiday in Louisiana, so many close then. Homestead filings can be made any time of year, but disputes are easiest during the fall inspection window, when the roll is open and staff expect questions. If you live far from the parish seat, ask whether the office accepts forms by mail or email.

Keep copies of everything you hand over, and ask the clerk to note the date and the name of the person who helped you. If the office promises a follow-up, write down the deadline.

Property assessor offices in Louisiana operate under state property tax statutes that specify how properties must be valued, how often reappraisals occur, and what exemptions are available to qualifying homeowners. The state department of revenue or taxation typically provides oversight and technical guidance to county assessors to ensure consistent valuation practices statewide.

Assessor locations are available in 73 cities across Louisiana. They are spread across 64 counties.

Cities with the highest concentration include New Orleans, Baton Rouge, Cut Off, where high real estate activity and complex commercial properties create greater demand for assessor services and property valuation resources.

Property owners in Louisiana should verify that their primary residence homestead exemption is active and confirm the annual appeal deadline with their local assessor office, as missing the deadline means waiting until the following tax year to contest a valuation.

Many county assessor offices in Louisiana now offer online property search tools where homeowners can view their assessed value, recent sales history, and exemption status without visiting the office. If you have questions about a recent reassessment notice, calling or emailing the assessor's office is often the fastest way to get a response before filing a formal appeal.

Assessor Offices in Southeast, Central and North Louisiana

Southeast Louisiana holds the densest cluster of offices. Along the Mississippi River, St. James Parish (5800 Highway 44, Convent, 225-562-2252) and St. John the Baptist Parish (2393 Louisiana 18, Edgard, 985-497-8788) cover both residential neighborhoods and industrial corridors, so one assessor may value very different property types. North of the lake, the Tangipahoa County office is in Amite City, and Washington Parish is at 908 Washington Street in Franklinton (985-839-7815).

In central and southwest Louisiana, Grant Parish is at 200 Main Street in Colfax (318-627-5471), Beauregard Parish at 214 West 2nd Street in DeRidder (337-463-8945), and Acadia Parish at 500 Northwest Court Circle in Crowley (337-788-8871). Farther north, Bossier Parish is at 204 Burt Boulevard in Benton (318-965-2213), Union Parish at 101 North Main Street in Farmerville (318-368-3232), Red River Parish at 615 East Carrol Street in Coushatta (318-932-4922), and Caldwell Parish at 201 Main Street in Columbia (318-649-2636).

Your mailing city does not decide which assessor you need; your parish does. A New Orleans address can fall in Orleans County or in Jefferson Parish, as the Jefferson office's own New Orleans mailing address shows. Check the parish printed on your tax bill or deed before you call.

Phone numbers and hours change, so confirm before you travel. A two-minute call can tell you whether the office needs an appointment, takes forms by email, or has a deputy assigned to your district.

Louisiana Assessor FAQs

Visit or contact the assessor in the parish where the home sits. You must own and occupy the house as your primary residence, and you generally need a recorded deed plus a photo ID or driver's license showing that address. The exemption removes the first $75,000 of market value from most parish taxes, which equals $7,500 of assessed value on a home. You file once, and it normally carries forward until you sell or stop living there. If you buy a new home, file again for it, and ask the office whether it requires any extra forms.

No. The assessor only determines value and maintains the roll. In Louisiana the parish sheriff serves as tax collector, so payments go to the sheriff's office, usually by mail, online or in person. Bills are generally issued in the fall and due before the end of the year, with interest and penalties after the deadline. If your mortgage lender escrows taxes, the lender normally pays on your behalf, but you should still check the roll for errors. For the amount owed or payment options, call the sheriff's tax department; for value or exemptions, call the assessor.

Start with the assessor. Ask for your property record card, compare it with the actual home, and bring comparable sales or repair estimates. If the assessor will not adjust the value, file a protest with the parish Board of Review during the annual inspection period. A decision there can be appealed to the Louisiana Tax Commission or to district court. Deadlines are short and set each year, so get the dates in writing. Remember that the assessor sets value, not the millage. A bill increase caused by a new millage cannot be fixed through an assessment appeal.

Louisiana is the only state organised into parishes rather than counties, a tradition that traces back to its Spanish and French colonial church districts. Parishes serve the same purpose as counties, and each elects its own assessor. Our directory labels some entries as counties for database consistency, but the office you need is the parish assessor. The Louisiana Constitution provides for these offices, and the Louisiana Tax Commission oversees them. When you search, use your parish name, such as Lafourche, Vermilion or Tangipahoa, and confirm the parish on your tax bill.

Yes, in addition to the standard homestead exemption. Owners aged 65 or older, and certain disabled owners, may qualify for a special assessment level that freezes the home's assessed value at a base year, subject to income limits. Applications go through your parish assessor, who will ask for proof of age or disability and recent income records. Separate exemptions exist for some disabled veterans. Rules and thresholds change, so ask the office for the current form. The freeze applies to assessed value, not to millage increases that voters approve.

Storm damage can change what a structure is worth, but the change is not automatic. The assessor updates records when buildings are demolished, rebuilt or substantially altered. If a hurricane or flood damaged or destroyed your home, contact your assessor, especially in coastal parishes such as Plaquemines, St. Bernard or Cameron. Bring photos, insurance claim papers and any demolition or permit records. Ask whether an adjustment or special relief applies for that tax year and how to file for it. Raise the issue before the annual inspection period ends, because corrections are simplest then.
